Highly Rarefied Gas: Free Molecular Gas and Its Correction

Part of the Modeling and Simulation in Science, Engineering and Technology book series (MSSET)


With an increase of the Knudsen number of the system, the effect of intermolecular collisions becomes less important. When their effect can be neglected, the gas (its state) is called a free molecular gas (free molecular flow). In this chapter, we discuss the free molecular flow and its correction by molecular collisions when external force is absent.
